I should have added that when the shack MBP is connected to the K3 and I
attempt rig control using RUMLog, it communicates with the K3 and
receives info such as freq even though it's in TX. So there's
communication there, I just can't stop the TX.

Strange issue and haven't found much by searching.
I use a MacBook Pro with my K3 and KX3. It had worked fine for rig
control and with the K3/P3/KPA utilities. I added an iMic audio
interface (bought it for the iPad and was experimenting) and setup
CocoaModem for use with the KX3 to do digital modes. When I connected
the MBP back to the K3, any type of USB activity for rig control or the
K3/P3/KPA utilities causes the K3 to go into TX which can't be stopped
except by unplugging the USB from the MBP. If there's no USB control
activity with an app, the K3 works normally.
I simplified the radio down to just the K3 with no other accessories and
it still happens. KPA utility works as expected with the KPA, even with
the K3 powered ok and it going into TX. I checked for grounding issues
and reseated all of the serial cables. The USB ports work normally for
everything except interfacing to the K3. I tried a different MacBook
with the K3 and it works fine, so it's something with the MBP side of
the USB connection on my shack laptop.
I then took a questionable troubleshooting action to test K3
communications, which I had planned to do anyway, was to move to the new
beta K3 firmware. I forced the K3 into MCU Loader and upgraded the
firmware with the shack MBP. No issues in communicating with the K3
during the upgrade. Once the K3 was back operational, same issue as
before with unexpected TX on rig control.
Anyone experience an issue like this before? Thought I'd ask before
stripping CocoaModem and related pieces off the shack MBP.
